CHANNEL-.CUTTING AND FLAP-TURNING MACHINE.

SPECIFICATION forming" part of Letters Patent No. 686,371, dated November 12, 1901.

I Application filed April a; 1897. Serial No. 634,577. (No model.)

To aZZ whom, it may concern.-

Be it known that LGEORGE ELMERWARREN,

of Pawtucket, in the county of Providence and State of Rhode Island, have invented a new and useful Channeling-Machine, of which the following is a specification, reference being had to the accompanying drawings,in which Figure 1 is a front elevation, and Fig.2 a. side elevation, of one of my machines which completes the channel in the outer sole of a boot or shoe-that is, not only cuts the channel, but also opens it and turns back its flap. Figs. 3, 4,5, and 6 are sectional details explanatory of the new mode of operation of my machine. Fig. 7 is an elevation of the mechanism for oscillating the flap-turner. Figs. 8, 9, 10, 11, 12, and 13 illustrate my invention as applied to turning the lip of a channeled inner sole. r

In the manufacture of welted shoes a slit or channel is cut at the edge or on one face of the outer sole, and it is necessary that the lip or flap be turned and pressed back to open the channel.

My invention consists in the combination of a channeling-knife, an oscillating flap-turner, and means for operating the knife and flapturner. The oscillating fiap-turner is also wholly new.

It is highly desirable that outer soles be channeled after they are laid-that is, after they are temporarily secured in place upon the lasted shoe in readiness for the stitcher or sewing-machine by which the welt and outer sole are sewed together, and I have shown in Figs. 1 to 7, inclusive, the best form of my machine for channeling outer soles after they are laid. In these figures, A is the shoe on the last, at the welt, and a the outer sole. The welt and outer sole are clamped between the work-holders B and b, one of which, 17, is fast to the frame of the machine, while the other, B, is preferably provided with a sleeve B, mounted to revolve on a stud b, and for greater steadiness and also to still further reduce friction I use an auxiliary sleeve 6 on stud b. To put the work in place between the work-holders, work-holder B and stud b are drawn away from work-holder b, and this and b are at the upper end of lever 12 which isfulcrumedouslideb Byliftingthe handle portion of lever 12 against the force of its spring, slide 17 is drawn down, carrying with it Work-holder B and stud b. After the work has been put in place it is fed by the levers D and b Lever D has the necessary motions imparted to it by the cams D D through arm (1 and its springcl and stud d cam D acting on the cam-roll of arms d to cause the feedfoot on lever D to press upon the work and lift oif of the work alternately, and cam D acting through stud d to move the lever D endwise, for lever D, arm (1, and stud d are fast to rock-shaft d which not only rocks, but also moves endwise. Lever b is moved to feed in connection with lever D by lever b which is actuated by the cam-groove of cam 19 As the work is thus fed the channeling-knife F cuts the channel and the lip or flap turner G oscillates, as best seen in Figs. 3 and 4, to turn the flap back and press it down sufficiently to prevent it from returning to place. The action of the channeling-knife is best seen in 5 and 6. The knife F is carried by lever b and aids in feeding on the feedstroke' of lever b while it cuts on the return stroke of lever 5 the Work being then held by the feed -foot on lever D and the lip turner G, which clamp the work between them on the back stroke of lever 19 which is the cutting stroke of knife F. The flap-turner G is fast to the segment g, which meshes with the rack g, and rack g is reciprocated by lever g and its cam 9 as fully shown in Fig. 7.

The operation of my machine as so far described is to cut the channel and press the flap back by the action of the knife and flapturner, and the front of the work-holder 1) acts as a guide for the work, the operator pressing the upper, near the welt, against the front of work-holder b, and the channel is thus made parallel with the upper and the side of the last.

Inner soles for welted shoes commonly have two channels, one at the edge and the other on the inner face of the sole parallel with the edge, and it is more convenient in many cases to make these two channels on the usual channeling-machine. For that reason I have adapted my lip-turner for use in turning the lip of the edge channel of inner soles, for it is usual to call the flap of this edge channel a lip rather than a flap.

In the machine shown in Figs. 8 and 9, whose work is illustrated in Figs. 10 to 13, inclusive, the work-holder is composed of two clamps j J, which are separable and the upper one of which, j, is at the end of feed-lever D while the lower clamp J is best made in the form of a disk adapted to rotate on its axis in order to reduce friction. The sole is fed, as above described, by the feed-lever D the axis of stud D imparted by cam D The rack g, which meshes with the teeth of segment 9, is reciprocated in Figs. 8 and -9 by lever G and cam G the link GB connecting rack g with lever G, and the work is guided by the guide G which extends under the lip of the channel, as will be clear from Figs. 10 to 13. i

What I'claim as'my invention is.

1 In a channeling-machine a channelingknife and an oscillating flap-tn rnerand means to cause the knife to cut the channel and the flap-turner to turn the flap over and press it down in its turned-over position substantially as set forth.

2. Achannel-flap turner, consisting of a tool shaped at one end to enter the channel and mechanism to oscillate that tool with the said end of the tool as the center of oscillation substantiallyasand for the purpose specitied.
